SPATIAL CALCULATION OF INELASTIC COMPOSITE BARS

Abstract

We consider the deformation calculation of inelastic composite bars of variable cross section along the length of variable-stiffness relationships shift. The solution is based on an overall A.R. Rzhanitsyn's theory of elastic spatial working composite rods. A formula to determine the equivalent modules strains previously obtained by the author, which taking into account the development of inelastic strains in wet composite rod, the compressibility and shear deformation of the material branches are used. The variable stiffness of the inelastic composite rod in torsion is taken into account.
